SPECIFICATION forming part of Letters Patent No. 391,705, dated October 23, 1888.

Application filed March 23, 1883.

Serial No. 89,270. (No model.)

To all whom it may concern:

Be it known that I, HENRY S. HACK, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Calendar, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

My main invention is a double-roll calendar consisting of a calendar-strip mounted upon two spindles which are connected by one or by two cross-pieces which extend between the spindles near the edge of the calendar-strip and form a frame either four-sided or three-sided, that part of the strip which extends between the spindles filling the frame either wholly or partially.

Heretofore the calendar-strip and its two spindles have been mounted in a box or case, as in Patents No. 77,837, of 1868, to Pooler, and No. 171,227. of 1875, to Keller, or have been mounted in four bearings each secured upon the face of a stiff sheet or backing, as described in an application for Letters Patent filed by me and now pending. Serial No. 47,615; but in the first of these classes of double-roll calendars only that portion of the front surface of the strip which is under a hole cut in the front wall of the box is visible, and, moreover, the box must necessarily be large enough to receive both spindles and the entire strip; and in the latter class the backing covers the rear surface of the strip and must be of a thickness and consequent stiffness sufficient to perform its function as a holder for the bearings, the spindles, and the strip. Calendars embodying my present invention differ from these two classes in that the two rolls are framed in an open frame, except as the opening is occupied by the calendar-strip, and this is the chief feature of my invention, its advantages being not only the marked difference in style from other classes of calendars caused by mounting the calendarstrip in a frame as distinguished from inclosing it in a box, as in Poolers and Kellers patents,

above referred to, or mounting it on a backing, as in the other class of double-roll calendars, but also the fact that both sides of the calendar-strip can be utilized, thereby requiring only one-half the length of paper neces sary in all calendars where but one side of the strip is utilized, and making the designs and ornamentation upon one side to be so widely different from those upon the other side as to make practically two calendars in one.

It will be understood by those in this business that it is desirable to make several different styles of calendarsas, for instance, for several different advertising purposes, as well as for use in offices and private houses, the latter being usually more costly and more highly ornamented than either of the others and for this reason I have shown in the drawings two forms of my invention.

Figure 1 is an elevation, Fig. 2 asection, and Fig. 3 a plan, of one form of calendar embodying my invention. Figs. 1 and 5 show in section an elevation and modification, and Figs. 6 and 7 are details.

It will be seen in all the drawings that the calendar-strip B is so wound upon the spindles A A that it extends from one side of one roll to the opposite side of the other roll, and

it is this arrangement which enables me to utilize both sides of the strip,and which con stitutes the distinguishing characteristic of my invention.

What I claim is The improved doubleroll calendar above described, consisting of a calendar-strip and its two spindles connected together to form two rolls, the strip extending from one side of one roll to the opposite side of the other roll, leaving both surfaces of that portion of the calendar-strip between the rolls visible, as and for the purpose set forth.

HENRY S. HACK.
